Macro delete_lines 

macro_rules! delete_lines {
    ($n:literal) => { ... };
    ($n:expr) => { ... };
}

Delete n lines at the cursor, moving the remaining from bottom.

Equivalent to CSI Pn M.

If used with literal, produces &'static str, otherwise produces String.

Example

let mut buf = formatc!("{'clear}");

buf += "line 1\n";
buf += "line 2\n";
buf += "line 3\n";
buf += "line 4";
buf += codes::move_up!(2);
buf += codes::delete_lines!(2);

println!("{buf}");

Result in terminal
